By using brine shrimp (Artemia salina) lethality test-guided fractionation, a single bioactive compound (LC(50)=26 ppm) was isolated from the 95% ethanol extract of the dried aerial parts of Impatiens balsamina L. and subsequently identified as 2-methoxy-1,4-naphthoquinone (MNQ). The structure of MNQ was confirmed by UV, FT-IR, MS, and 1-and 2-D NMR(More)
Suberin is a biopolymer present in some plant cell walls that modifies their biophysical properties. It contains both poly(phenolic) and poly(aliphatic) domains that are unique and distinct in both their chemical composition and tissue and sub-cellular location. The biosynthesis of the suberin poly(phenolic) domain is hypothesized to follow a(More)
